Spike Chaser is annoying but there are some ways to deal with it.
My Favorite is Optic Barrel, if you are close enough to tag her with it, you get a free approach due to knockdown, if you wanna be a tad more fancy, you can Projectile Clash the Spikes with OB and cancel both of them out.
When in doubt, just Super Double Jump Barrier, sure it will give Lambda a free 2D attempt, but you wont lose a primer at the very least.
Also note that the OB solutions are on reaction, if you see her start it up, throw out an OB(if you wanna hit her) or throw out an 236B after the spikes release to cancel them out.
If she decides to throw them out at close range(I dunno maybe to bait a drive or something) you can either Microdash 5A > 6A combo(if you can react to it fast enough), or if you're a bit too slow on the draw, you can 5B > Jump Barrier, which is if the spikes keep coming out after you tag her.
